Functional Dysphagia

Functional dysphagia is the sensation of solid and/or liquid foods sticking, lodging, or passing abnormally through the esophagus. It is diagnosed based on symptoms present for at least three months and not associated with anatomic abnormalities, gastroesophageal reflux disease (GERD), or well recognized motility disorders such as achalasia [difficulty swallowing due to an absence of peristaltic contractions in the esophagus].
